Measurements of the CKM angle $\gamma$ at LHCb

These proceedings describe two LHCb measurements of the CKM angle $\gamma$: a measurement with $B^0\to D K^{*0}$ decays where the $D$ meson decays into two- and four-body final states, using proton-proton collision data corresponding to an integrated luminosity of $5\,\text{fb}^{-1}$, and a measurem...

description These proceedings describe two LHCb measurements of the CKM angle $\gamma$: a measurement with $B^0\to D K^{*0}$ decays where the $D$ meson decays into two- and four-body final states, using proton-proton collision data corresponding to an integrated luminosity of $5\,\text{fb}^{-1}$, and a measurement using $B^\pm\to DK^\pm$ decays where the $D$ decays into the final states $K_\text{S}^0\pi^+\pi^-$ and $K_\text{S}^0K^+K^-$, using data corresponding to an integrated luminosity of $2\,\text{fb}^{-1}$. Furthermore, the combination of all LHCb measurements of $\gamma$ is described. This combination constitutes the world-leading, single-experiment direct determination of $\gamma$ and obtains the value $\gamma=(74.0^{+5.0}_{-5.8})^\circ$.
